使用PowerShell 2.0映射驱动器监控

我正在编写PowerShell 2.0脚本，以监视和重新连接应映射的网络驱动器。它主要起作用。一旦确定某个驱动器已断开连接，我的登录脚本（ptt.vbs）将运行并重新映射驱动器。但是，在这之后，即使重新映射，它仍会继续看到特定的驱动器号断开连接

while($true) {
  $disconnectedDrives = @()
  $mappedDrives = 'J:', 'R:', 'S:', 'W:'
  foreach ($drive in $mappedDrives) {
    if (-Not (Test-Path $drive)) {
      $disconnectedDrives += $drive
    }
  }
  if ($disconnectedDrives) {
    Write-Host "$disconnectedDrives not mapped."
    Write-Eventlog -LogName 'Windows PowerShell' -Category 3 -source PowerShell -eventID 601 -EntryType Error -message "$disconnectedDrives OFFLINE and not available."
    \\dc1\NETLOGON\ptt.vbs
  }
  Start-Sleep 1
}

知道我做错了什么吗？

对我来说，VBS和Powershell的混合是可疑的

但至少a会采取不同的方式。首先创建一个包含网络驱动器配置的中心文件。例如“\dc1\NETLOGON\ptt.csv”可以如下所示

J;\\srv1\shareA
R;\\srv1\shareB
S;\\srv2\shareA
W;\\srv2\shareB

这是剧本
